圖書簡介
全書共分為兩部分,第一部分為前6章,作者從人們對生產設備手動操作的實際經驗出發,系統地介紹了控制原理、控制設備和控制系統的基本概念。在測量信號的變換和處理方面,把工業儀表中的模擬電路、可程式控制器(PLC)及信號採集系統中的數字電路結合工業電子學中的基本理論融會貫通加以介紹。在測量信號的獲取方面,重點對溫度、機械量和光學感測器的原理、器件、特性和套用進行丁詳細的分析。書中第二部分為後6章,首先講述了控制信號的類型和執行器,接著重點介紹了離散、連續、計算機及匯流排網路控制系統的構成、特點和技術指標。結合系統的要求,講解了PLC的原理和編程方法,位式控制、PID概念及模擬調節器,工業控制計算機硬體、軟體的配置等內容。最後介紹了串級和多變數控制系統以及系統的調節質量評定和調節參數的整定方法。
